Old EF-S lenses through an adapter work well, but there is a nuance - the camera constantly focuses, and, moreover, constantly turns the focus of the lens - I think this drains the battery even faster. On a standard lens, this is imperceptible, there the ring only works when manual focus is turned on. Pros: Dimensions, ease of use, functionality, photo quality, WiFi and Bluetooth. Has some cons The battery is not very capacious, there is no USB charging, 4K video is only from the center of the matrix, and only with contrast focusing.
